The invention relates to a high pressure fuel accumulator for an accumulator injection system in internal injection engines, comprising a base body which is provided with a longitudinal recess which has a plurality of connecting bores emanating therefrom. The inner chamber of the longitudinal recess is essentially cylindrical in shape and has at least one rib shaped section on the inner perimeter of the longitudinal recess into which a connecting bore formed in the longitudinal recess leads.

High-pressure fuel reservoir for a reservoir injection system

An injection system for an internal combustion engine comprises a valve arrangement ( ), connected to an inlet ( ) to a high pressure pump ( ), which regulates the flow of fuel for lubricating and cooling the high pressure pump ( ) and bleeds the injection system. The valve arrangement ) comprises at least one displaceable actuator and a first and second throttle device ( ). The actuator ( ) is regulated according to a pressure of the fuel flow between a feed supply pump ( ) and the high pressure pump ( ), such that a first connection to, the high pressure pump ( ) is opened, by means of the first throttle device ( ), or the feed ( ) to the high pressure pump ( ) is interrupted, or a second connection to the high pressure pump ( ) is opened, by means of the second throttle device ( ). The invention further relates to a method of bleeding and/or regulating said injection system.

Injection system for an internal combustion engine and method for regulating and/or bleeding of said system

An apparatus for producing a variable volumetric flow in a fuel feed system includes a high-pressure pump having at least one inlet, at least one cylinder, at least one piston each moveable in a respective cylinder, and a shaft driving the at least one piston. A metering device is disposed in the at least one inlet of the high-pressure pump, is synchronized with the shaft and feeds a variably meterable volume of fuel to the at least one cylinder during each revolution of the shaft. Metering is performed by varying an angle between opening and closure of the at least one inlet.
